tLlLCiiXNlZEFil SPECIFICATION forming part of Letters Patent No. 776,979, dated December 6, 1904. Application filed September 30, 1904. Serial No. 226,662. (No model.)

To n/ZZ 'l1/7mm it may] concern,.-

Bc it known that l, JOHN K. VVILLI'AMs, a citizen ot' the United States, residing' at Akron, in the county of Summit and State of Ohio,

have invented a certain new and useful Improvement in Vulcanizers, oi" which the t'ollowing' is a complete specilieation.

lVly invention relates generally to vulcan izers, and has especial relation to devices to be used in connection therewith.

The common form of vulcanizers for longlength articles embodies two boxes or members arranged to register with each other and having through their abutting faces longitudinal grooves partly in each member into which the material to be vulcanized is placed. These members are provided with chambers into which a heating medium is introduced to cause vulcanization, and the two are clamped 2O tog-ether by suitable clamping devices during the process. These vulcanlzers being limited in length are only capable oi' producing' indelinite lengths ot' material-such as tires, hose, --by recourse to the following method, which consists in placing' inthe vulcanizercavities strips of material which protrude considerably from one end, and which ends are not cured with the portion in the vulcancanizer, but remain g'recn. Each strip is re moved after curing' and the green unvulcanized end inserted into the opposite end oi' the vulcanizer and made to abut against the end of an entirely new strip of material whose end protrudes in the same manner from the vulcanizer that the lirst one did. The members after being clamped together again are heated, and the green end of the first strip unites during' the process of curing to the end of the second strip, and all ot' the second strip eX- 40 cept the protruding end is cured simultaneously with the making of the joint between the two strips. This is kept up until a strip of any desired length is obtained.

lt has been found difficult to keep the protruding ends of the strips outside oi' the members cool enough to prevent a partial vulcanization thereof, which interferes seriously I with the operation oi' joining the ends oi the strips, and hence the object oi" my invention is to place on thc ends ot' the vulcanizer mem- 50 bers or form integral therewith suitable means to prevent this partial heating' or curing of the protruding ends.

Another object of my invention is to make the cooling-chambers formed at the ends oir the vulcanizer members available as heating chambers instead ot' cooling-chambers where the vulcanizer is to produce single-length tires as contradistinguished from continuouslength tires.

ln accomplishing' the aforesaid objects I employ certain mechanism, 'forms ot which are hereinafter described, reference being had to the accompanying drawings, which form a part hereof.

In the accompanying drawings, in which similar reference-numerals indicate like parts in the different ligures, Figure 1. a side clevation of a vulcanizer with my cooling device, having portions thereof broken away at the line X of Fig. 2. Fig. 2 is an end elevation looking from the right oi' Fig 1.

The members l and 2 are clamped together in any preferred manner. The ordinary means used are a series ot' bolts 3, passing' through 75 slotted lugs i on the sides of the members l and 2.

In the members l and 2 are heating-chan1- bers 5 and 6, respectively, in which a heating' medium is introduced, causing' vulcanization, 30 and 1nold-cavities for holding' the material are formed longitudinally along` the abutting faces of the two members, partially in each mem ber in the metal existing between the chambers 5 and 6.

Ii' it is desired to make or `form a coolingchamber at the end or ends of this ordinarilyformed vulcanizer available likewise as a steam-chamber, .l cast or otherwise manufacture integral with the two members l and 2 90 cooling-chambers 7 and r3, separated from the heating-chambers 5 and 6 by double walls 9 and lO and ll and 12. The spaces between the walls 9 and l() and 10 and l2 constitute air-passages to assist in keeping the extended ends of the green tires cool enoug'h to pre- Vent partial Vulcanization.

The metal existing' immediately above and below the mold-cavities and which also connects the cooling-chambers 7 and 8 with the main bodies of the members of the vulcanizer is of full width with the vulcanizer members, and these chambers 7 and 8 are also held to the Vulcanizer members by integ'ral lugs 13 and 1&1, which need not be the full width of the vuleanizer members unless for eXtra strength.

Extending from either side of the cooling'- chambers 7 and 8 are inlet and outlet pipes 15 and 16, by which a cooling fluid is carried into and withdrawn from the interiors or' these chambers 7 and 8.

Thus it will be seen that in addition to the action of a cooling' fluid, such as water, passing through the chambers 7 and 8 the airspaees between the chambers 7 and 8 and the members 1 and 2 also assist in keeping' the temperature below a Vulcanizing heat in the extended ends of the tires held between the cooling-chambers 7 and 8.

Should it be desirable at any time to employ the entire vulcanizer, thus including the cooling-Chambers, as a simple Vuleanizer for making single-length tires, a pair of holes 17 are drilled in the ends of the heads of the chambers 7 and 8, partially in the top and bottom walls thereof, into Chambers and 6, and after closing' the openings for the reception of the inlet and outlet pipes 15 and 16 by plugs a heating medium may be introduced through the openings 17 to fill not only the cooling'- cliambers 7 and 8, but also the chambers 5 and 6. '1

1V hat I claim, anddesire to secure by Letters Patent, isw

1. A vulcanizer Consisting' or' mold members adapted to meet and register, each individually capable of being heated, and a eooling-chamber at the end thereof and separated from the heating-chambers by an air-space.

2. The combination oi' a vulcanizer having' two parts arranged to meet and register and provided with mold-cavities formed in their meeting' faces and cooling-chambers at their ends and separated from said parts of said vuleanizer by an intervening' air-space.

3. A mold member for vulcanizers consisting of a heating-chamber and a cooling-chamber separated by an interposed air-space.

4. A Inold member for vulcanizers consisting' of a heating-chamber and a cooling-chamber separated by an interposed air-space, said cooling-Chamber being Convertible into a heating-chamber.

5. The combination in a twopart separable vulcanizer, of a cooling-chamber formed in the end thereofl and means for introducing to said chamber a cooling' medium.

ln testimony that l claim the above I hereunto set my hand in the presence of two subscribing witnesses.

JOHN K. WILLlAMS.
